Specification of Letters Patent No. 14,429, dated March 11, 1856.

of, reference being had to the accompanying' drawings and to the letters of reference marked thereon.

The nature of my invention consists in so constructing a stop-cock, that whenever there is any pressure in the pipe to which Vit is attached, beyond a certain number of pounds to the square inch, it will open and let the water escape at the same place where it is drawn when required for use. Also in the manner of applying the eccentric be'- tween two projections on the cap to raise t-he piston-valve and cause itl to stand open, or be self-closing, at option.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

At the junction of the spout S, Figure 4, of the accompanying drawings, I make the spacea little larger than the piston, immediately below this space VI form the valve seat, with a perfect ground joint, and immediately above the space, I bore it out perfectly cylindrical to t the piston V, which is packed with the packing p, p, and is kept tight by the pressure of the spring s, upon the follower fw. In this case it is necessary that the water should come in at o, and press with its full force against the bottom of the p-iston valve V. The piston-rod is turned around and straight, and passes through a round hole in the center of the cap c, and terminates in an eccentric wit-h a throw sufficient to raise the piston its required height, and turns between two projections t, t, Fig. 1, on the cap; these projections serve to keep the eccentric in its proper position, and prevent the pin that connects it with the piston rod from coming out.

By carrying the lever L, Fig. 4, to the position of the dotted lines, the eccentric would then be upon its dead point farthest from the center around which it turns, and would consequently stand in that position, until turned off of its center, when it will close of itself. The spiral spring s, is fitted loose to the piston rod, and cylinder; and is wound open, the ends squared, and forced together, and the remaining elasticity is permanent. I then measure the spring without any pressure upon it, then p-ut upon the spring, the exact weight required upon the pistonto give the number of pounds pressure to the square inch in theA pipe required, and the difference between the two measurements of length, with the weight, and without it, is the exact length to have, the spring, more, than the dist-ance between the follower w, and cap c. By unscrewing the cap c, all will come out together.

The combination of the handles constructed as specified, with the Stem and the spring when the latter is placed behind the valve, substantially as Set forth.
